Self-employed borrowers don't get locked into higher rates by default.
The challenge lies in how lenders assess your income and risk profile, not the fact that you run your own business. When you understand what drives your interest rate and how to present your application, you gain access to the same loan products and pricing available to any borrower.
How lenders calculate your interest rate as a self-employed borrower
Your rate is determined by your loan to value ratio, the type of loan you choose, and how lenders assess your income stability. A borrower with a 20% deposit applying for an owner occupied home loan will typically access lower rates than someone borrowing at 90% LVR, regardless of employment type.
The difference for self-employed applicants is how income is verified. Lenders want to see at least two years of tax returns, and they calculate your income using your taxable profit after deductions. If you've claimed significant business expenses to reduce your tax, your declared income may not reflect your true earning capacity, which can affect both your borrowing capacity and the loan products available to you.
Consider a plumber in Sydney's Inner West who earns $140,000 annually before deductions but claims $35,000 in vehicle, tools, and travel expenses. On paper, their taxable income sits at $105,000. That lower figure is what most lenders use to assess the application, which affects both the amount you can borrow and the rate you're offered.
Variable rate versus fixed rate: which suits your business cycle
Variable rates move with the market and typically sit lower than fixed rates when the cash rate is stable or falling. Fixed rates lock in certainty for one to five years but remove flexibility if your income fluctuates or you want to make extra repayments.
For self-employed borrowers, a variable rate offers the flexibility to make lump sum payments during strong income months without penalty. If your business experiences seasonal variation or irregular cash flow, that ability to reduce your principal when funds are available can save significant interest over the life of the loan.
Fixed rates work when you want certainty around repayments and plan to hold the property long term without making extra payments. The trade-off is reduced flexibility and potential break costs if you need to refinance or sell before the fixed term ends. You can read more about this in our article on fixed rate expiry.
Split loans and how they reduce risk for variable income earners
A split loan divides your borrowing between fixed and variable portions. You might fix 50% of your loan to lock in a portion of your repayments, while keeping the other 50% variable to allow extra payments during high income periods.
This structure suits business owners who want some repayment certainty but don't want to lose the ability to pay down debt when cash flow allows. The fixed portion protects you if rates rise, while the variable portion lets you take advantage of an offset account and make unlimited additional repayments.
In our experience, self-employed clients with irregular income often split 40% to 60% fixed and the remainder variable. The exact split depends on your business cycle, risk tolerance, and whether you expect to have surplus funds to reduce the loan faster.
Offset accounts and why they matter more when your income varies
An offset account is a transaction account linked to your home loan. The balance in that account reduces the interest charged on your loan without locking those funds away. If you have $30,000 in your offset and owe $500,000 on your home loan, you're only charged interest on $470,000.
For self-employed borrowers, this feature is critical. Business income can arrive in large amounts sporadically, and an offset account lets you reduce interest costs immediately without committing those funds permanently. You retain access to the money for business expenses, tax payments, or unexpected costs while still building equity in your property.
Variable rate loans and the variable portion of split loans typically allow a linked offset. Fixed rate loans generally do not. If you expect to hold surplus cash at any point during the year, a loan structure that includes an offset will outperform a fixed-only loan, even if the fixed rate appears slightly lower.
Interest rate discounts and how your deposit size affects pricing
Lenders price loans based on risk, and your deposit is the clearest indicator of that risk. Borrowers who provide a 20% deposit or more avoid Lenders Mortgage Insurance and access the lowest available rates for their chosen loan type.
If you're borrowing above 80% LVR, you'll pay Lenders Mortgage Insurance and typically receive a higher interest rate. The difference can range from 0.10% to 0.50% depending on the lender and how far above 80% you're borrowing. That margin compounds over time, so increasing your deposit from 10% to 20% doesn't just remove the LMI premium, it reduces your ongoing interest cost across the life of the loan.
Self-employed borrowers often have capital tied up in their business. If you're weighing up whether to pull equity from your business to increase your home loan deposit, calculate the interest saving against the cost or opportunity lost by reducing business capital. In many cases, the reduction in LMI and interest rate justifies the shift, but the decision depends on your business cash flow and growth plans.
How your loan structure affects future refinancing and rate changes
A portable loan allows you to take your existing loan with you if you sell and purchase another property. This feature matters if you're locked into a fixed rate and need to move before the fixed term ends, as it lets you avoid break costs.
Most variable rate loans are portable by default. If you're considering a fixed rate or split loan, confirm portability with your lender before committing. For self-employed borrowers, this flexibility can be the difference between being able to upgrade or downsize in response to business changes and being locked into a property because exiting the loan early would trigger tens of thousands in penalties.
When your fixed rate expires, your loan will revert to the lender's standard variable rate unless you actively refinance or negotiate a new rate. Standard variable rates are typically higher than the discounted rates offered to new customers, so reviewing your loan every two to three years keeps your rate aligned with current market pricing.
What to prepare before you apply for a home loan
Lenders assess self-employed applications using your tax returns, business financials, and sometimes your Business Activity Statements. The stronger your documentation, the more confident lenders are in your income, and the wider your access to loan products and pricing.
Have your last two years of personal tax returns, your business tax returns, a profit and loss statement, and your most recent BAS ready before you apply. If your taxable income has been reduced by significant deductions, be prepared to explain your business structure and true cash flow. Some lenders will consider alternative income verification methods, but those options are limited and often come with higher rates.
If you're planning to apply for a home loan within the next 12 months, speak to a broker about how your current tax strategy will affect your borrowing capacity and rate. Adjusting your deductions for one financial year can open access to better loan terms and save more in interest than you'd gain from the tax deduction itself.

Frequently Asked Questions
Do self-employed borrowers pay higher interest rates on home loans?
Not automatically. Your rate is determined by your deposit size, loan structure, and how lenders assess your income. Self-employed borrowers with strong financials and a 20% deposit access the same rates as any other borrower.
Should I choose a variable or fixed rate home loan if I'm self-employed?
Variable rates offer flexibility to make extra repayments when cash flow is strong, which suits borrowers with irregular income. Fixed rates provide repayment certainty but limit flexibility. A split loan combines both.
Why does my deposit size affect my home loan interest rate?
Lenders price loans based on risk. A deposit of 20% or more avoids Lenders Mortgage Insurance and qualifies you for lower rates. Borrowing above 80% LVR increases both your upfront cost and ongoing interest rate.
What is an offset account and why is it useful for self-employed borrowers?
An offset account is linked to your home loan and reduces the interest charged based on the balance you hold. It lets you reduce interest costs without locking funds away, which suits borrowers with variable income who need access to cash.
What documents do I need to apply for a home loan as a self-employed borrower?
You'll need at least two years of personal and business tax returns, a current profit and loss statement, and recent Business Activity Statements. Strong documentation improves your access to loan products and competitive rates.
